For those developers who supported the Google Glass project early on by ponying up $1,500 to buy a developer set, Google will be hosting two hackathons, one in San Francisco and one in New York City, where early backers will be able to go hands on with early prototypes of the wearable computing devices.

Google's hackathon in San Francisco will take place January 28 and 29 and the hackathon in New York City will take place shortly after on February 1 and 2. The events are called Glass Foundry, a fitting name for the hackathons, and both events appear to follow the same agenda.

The first day will introduce the device and let developers use it on-site. After that, the hackathons will dive into the Mirror API and development with Google engineers at attendees' sides to answer any questions. Space is limited, so if you put out the $1,500 to get an early pair, you should get in contact with Google before all the slots are taken.
